Abstract: A temperature controlling system adapted for a projection apparatus is provided. The projection apparatus comprises at least a heat generating element, while the temperature controlling system comprises a liquid flow system, a heat generating device, and a heat transferring device. The liquid flow system is disposed along the heat generating element. The heat generating device produces heat with a positive value (endothermic) or a negative value (exothermic) in response to an environment dependent on the location of the projection apparatus. The heat transferring device transfers the heat generated by the heat generating device along the liquid flow system. The present invention maintains the operation of the projection apparatus under the desired working temperature and enables a thermal equilibrium of the projection apparatus without being influenced by the over-temperature or under-temperature of the external environment.

Abstract: The bio-expression system comprising: a process system used to process data and a three-dimension image generating module embedded in the computing system, wherein while input of a set of two-dimensional individual model sections is fed into the process system, the three-dimension image generating module is responsive to the input of the two-dimension individual model sections and is capable of processing an individual model construction and model-averaging procedure, thereby generating an average model for each individual dataset. A database includes a bio-expression sub-database, cellular network sub-database and fine structure sub-database, wherein the database is coupled to the process system to store at least the average model. A stereoscopic projecting system is coupled to the process system to display stereoscopic images for active or passive virtual reality applications, thereby presenting the bio-expressions, cellular networks or bio-fine structures under the input instruction of the process system.

Abstract: An improved projector device and the cooling device therefor are provided. The provided projector device includes a light source including a lead wire, a first foil having a first front-end and a first rear-end, and a second foil having a second front-end and a second rear-end, and includes a first blower configured on a first side of the light source and generating a first air to cool the bulb portion and the second foil of the light source, and a second blower configured on a second side of the light source and generating a second air to cool the lead wire as well as the first foil.

Abstract: The present invention discloses a light-shielding heat-dissipating mask for a projector. The projector has a light source, a fan, and an air vent. The light-shielding heat-dissipating mask comprises a plurality of metal sheets which are positioned at the air vent for dissipating the heat generated by the light source and decreasing the possibility of the light emitted form the light source escaping out of the air vent.

Abstract: An electronic apparatus includes a casing, a light source housed in the casing, and a heat dissipation device positioned between the casing and the light source. The casing is formed with a lead angle on its corner to create an inclined surface. The heat dissipation device has a first and a second end surfaces opposite to each other and a sidewall connected between them. The sidewall of the fan frame neighbors the inclined surface and has a slanting direction substantially paralleled to the inclined surface.
